`To a/Z whom it may concern:

,Be it known that I, MILES WIL'BERT l/VIL- LIAMs, a citizen of theUnited States, residing at Sharon, in the county of Mercerand State ofPennsylvania, have invented certain new and useful Improvements inRail-Joint-Base Bonds; and I do hereby declare the following to be afull, clear, and exact description of the invention, such as will enableothers skilled in the art to which it appertains to make and use thesame.

-For rail-joints I have' produced a novel bondin device whereby themeeting ends of the rais are firmly connected and lsecured and a joiningmaintained bya wedge action of the bonding device drawing the rail endstogether andA bracing them against-sidewise displacement. The bondingdevice crosses the rail-joint and is secured in grooves having vertlcalinclined shoulders in the base of each rail, and its construction is.such that it forms-a duplex Wed e, and for that purpose each end has ashoulgdered and a wedge form acting with a compoundffunction on eachrail-that is to say, drawing the rail en ds together and preventingtheir separation-the object being to dispense with the bolts employed tofasten the rail ends, the chairs, and fish-plates together. Incombination with the duplex-wed e bond a box-chair is employed to hold te rail ends down and laterally, while the wedge-bond holds themtogether, making a smooth-tread joint and preventingljar to the passingtrain. for it is a distinguis Ing feature of the duplex-wedge bond thatit causes the weight of the train on either end of the joint to act todraw and hold the rail ends together in crossing the joint.

The accompanying drawings illustrate my invention, and in whichy Figure1 shows the rail ends invertedand a base-groove in each terminating in avertical socket in the web. Fig. 2 is a tudinal section of therail-joint, its bonding device, and joint-supporting chair. Fig. 3 is ahorizontal section of the rail-joint, bolnding lig. 4 shows .the bondingdevice In side and end views. Fig. v5 is a vertical cross-section of therail-joint, its bonding device, and jointsup ortin chair.

T e we of each rail end has avertical base-groove 1, open at the end ofthe rail and terminating in a vertical socket 2 within the web. Thissocket joins the groove on each vertical longiside by a verticalshoulder 3, Fig. 3, which stands inclining upward from the base of therail and away from its end, and the socket preferably tapers from itsbase to its upper 6o end. Each groove, with its terminal socket, extendsabout three inches within the web and terminates in the web at the baseof the rail-head. The bonding device'consists of a web 4, adapted vtofit the -groove in each railweb and therefore crosses the rail-joint andhas an abutment 5 at each end, which partially iills the end sockets ofthe web-grooves, each abutment forming-a shoulder, inclining upward fromthe base toward theend of the web, so that it has a wedge action on theshoulders of the socket of each rail-web, the action of which ininserting the bonding device in the grooves is to draw and secure therail ends' together, the wedge action being such as to draw the jointtighter under the weight of the moving train. The web-abutments and thegroove-shouldersv afford security against the endwise separation of therails,` While the bond-weband its end abutments aord securityagainstlateral se aration of the rails. Moreover, the wedge orm of thebond-abutments provides a firm connection for the rail ends, and asaiding in this function the web ofthe bond is made of wed e form incross-section, and it will be noted t iat the base of the bonding deviceis on a plane with= the base of the rail-flan es. The chair is ofthe f0X type, having its rail side braces or fish-plates 7 integral withthebase-plate 8, the ends of which project beyond the ends of the sidebraces and are formed with depending flanges 9, which iit against andare spiked to the opposite sides ot the cross-tie, While each side edgeof the projecting ends of the base-plate has a notch or recess l0 toreceive spikes 11, driven into the cross-tie, so that the chair isfastened to the rail-flanges and to the cross-tie both endwise andsidewise. Openings 12 may be made in the side edges of the braces toreceive spikes 13, driven into the cross-tie, and these` several meansof securing the chair to the rail may be used together, rendering theboxchair a iirm and durable fixture to the crosstie. Looking at Fig. 2the lower edge of the bondin0F device is seen resting u on the baselateoi:j the box-chair, and as t e web of the bonding device is wedge-shapedin cross-section and its end abutments form wedges the I 1c weight ofthe rails will constantly tend to force the web and its abutments intothe rail lOO IOS

grooves and sockets, while the weight upon the rails keeps them down onthe bond. Obviously the rail-sockets and the bondingabutments may be ofany suitable form so long as thcy are adapted to coact in awedge laction for drawing the rail ends togther.

vertical socket within the I claim* 1. In a raiLjoint, the meeting endshavinvr each a vertical base-groove open at the en of the rail, andterminating in an enlarged web, tapering upward from the base of therail and forming a vertical shoulder on each side of the grooveinclining upward from the base and from the end of the rail, and abonding device formed of a web fitting the rail-grooves and having ateach end a vertical abutment fitting the tapering sockets of thegrooves, each abutment having a shoulder on each side of the webabutting the inclined shoulders of the railgrooves, whereby the bondingdevice is caused to have a wedge action on each rail to draw and holdthem together at the oint.

l2. In a rail-joint the meeting ends having each a vertical base-grooveopen at the end of the rail, terminating in an enlarged vertical socketwithin the web and having a vertical shoulder on each side of thegroove, and a bonding device formed of a web fitting the rail-groovesand having at each end an abutment .fitting the vertical sockets of thegrooves and having a shoulder each side of the web adapted to coact withthe shoulders ofthe rail-grooves to cause a Wedge action to draw andhold the rail ends togethei` at the joint.

3. In a rail-joint the meeting ends having each a vertical base-grooveopen at the end of the rail and terminating in an enlarged verticalsocket within the Web formi-ng a ver# ltical shoulder on each side ofthe groove, a bonding device formed of a web having at each end anabutment fitting the vertical sockets of the grooves and having ashoulder on each side ofthe web, the said shouldersef the grooves and ofthe adacpted to have a wedge action to draw and vertical wedge-formedshoulder on each side of the groove, a bonding device formed, ofavertica web fitting the rail-grooves and having at each end aWedge-formed abutment fittingthe vertical wedge-formed sockets of thegrooves, and a base box-chair having its ends turned down and spiked tothe opposite sides ofthe cross-tie and otherwise spiked thereto and tothe rail-flanges.

5. In a rail-joint, the meeting ends havin each a verticallJase-grooveopen at the end of the rail, terminating in an enlarged vertical socketWithin the web and forming a vertical shoulder on each side ofthegroove, and a bonding-web fitting the railrooves and having at each enda vertical a utment fitting the sockets of the grooves, each abutmenthaving a shoulder on each side of the web abutting the shoulders of therailgrooves and adapted to coact with them in causin a wedge actiondrawing and holding the rai s at the'joint, lin combination with abox-chair supporting the rails `laterally, an means for fastening thechair endwse, sidewise and verticallly.

In .testimony whereof I have signed my bonding-abutments the railstogether and the grooves andY name to this specification in the presenceof two subscribing Witnesses.
